Windows Explorer, with the name on ; for example, Bill_USB on HP04ab598100ff. There are three restrictions to this type of redirection. ● The device will not appear in the taskbar on the remote host with an icon to eject the device. Because of this, make sure to give the device a sufficient amount of time to sync data after a copy before removing the device to be sure that the device does not corrupt. Typically, less than one second is required after the file copy dialog finishes, but up to 10 seconds might be required depending on the device write speed and network latency. ● Only file systems supported by the thin client will be mounted. The supported file systems are FAT32, NTFS, ISO9660 (CD-ROMs), UDF (DVD-ROMs), and ext3. ● The device will be treated as a directory; common drive tasks like formatting and modification of the disk label will not be available. USB redirection of storage devices can be disabled in an individual connection's settings. If desired, you can disable mass storage redirection altogether. To do this, turn off USB redirection, and then change the registry keys as described in the following table. Registry entry root/USB/root/holdProtocolStatic root/USB/root/protocol Value to set 1 local Description Makes sure that the USBR type will not be automatically changed when a connection is set or unset Makes sure that the RDP connection does not attempt to redirect any devices to the remote session To completely disable local mounting of USB mass storage devices or to disable the redirection of USB mass storage devices but still allow other devices to redirect, in the thin client file system, delete the udev rule /etc/udev/rules.d/010_usbdrive.rules. RDP printer redirection By default, RDP has two methods of printer redirection enabled: ● USB redirection-Any USB printer plugged into the device will show up as a local printer in the remote session. The standard printer installation process must happen in the remote session if the printer is not already installed on that remote host. There are no settings to manage locally. ● High-level redirection-If either USB redirection is unavailable on the remote host or the printer is a parallel or serial printer, use high-level redirection. Configure the printer to use a local printer spooler, and the RDP client automatically sets up a remote printer that sends print spooling commands through a virtual channel from the remote host to the thin client. This method requires both that the printer be configured on the thin client and a Windows driver be specified on the thin client because the RDP client needs to specify to the remote host which driver to use for the remote printer. This Windows driver must match the driver that the printer would use when locally attached to a Windows operating system. This information is usually found under the Model in the printer properties.

Windows Explorer, with the name
<device label> on <client hostname>
; for example,
Bill_USB on HP04ab598100ff
.
There are three restrictions to this type of redirection.
●
The device will not appear in the taskbar on the remote host with an icon to eject the device. Because of
this, make sure to give the device a
sufficient
amount of time to sync data after a copy before removing
the device to be sure that the device does not corrupt. Typically, less than one second is required after
the
file
copy dialog
finishes,
but up to 10 seconds might be required depending on the device write speed
and network latency.
●
Only
file
systems supported by the thin client will be mounted. The supported
file
systems are FAT32,
NTFS, ISO9660 (CD-ROMs), UDF (DVD-ROMs), and ext3.
●
The device will be treated as a directory; common drive tasks like formatting and
modification
of the
disk label will not be available.
USB redirection of storage devices can be disabled in an individual connection's settings. If desired, you can
disable mass storage redirection altogether. To do this, turn
off
USB redirection, and then change the registry
keys as described in the following table.

changed when a connection is set or unset

Makes sure that the RDP connection does not attempt to
redirect any devices to the remote session
To completely disable local mounting of USB mass storage devices or to disable the redirection of USB mass
storage devices but still allow other devices to redirect, in the thin client
file
system, delete the udev
rule
/etc/udev/rules.d/010_usbdrive.rules
.
RDP printer redirection
By default, RDP has two methods of printer redirection enabled:
●
USB redirection
—Any USB printer plugged into the device will show up as a local printer in the remote
session. The standard printer installation process must happen in the remote session if the printer is not
already installed on that remote host. There are no settings to manage locally.
●
High-level redirection
—If either USB redirection is unavailable on the remote host or the printer is a
parallel or serial printer, use high-level redirection.
Configure
the printer to use a local printer spooler,
and the RDP client automatically sets up a remote printer that sends print spooling commands through
a virtual channel from the remote host to the thin client.
This method requires both that the printer be
configured
on the thin client and a Windows driver be
specified
on the thin client because the RDP client needs to specify to the remote host which driver to
use for the remote printer. This Windows driver must match the driver that the printer would use when
locally attached to a Windows operating system. This information is usually found under the
Model
in
the printer properties.
NOTE:
See
Serial or parallel printer
configuration
on page
64
